However, the traditional programming education method has a high threshold, has certain requirements on the age and the logic abstraction capability of students, and needs to be performed by depending on a computer programming language environment or a hardware method such as a tablet computer. The conventional programming environment requires text input through a keyboard, is inconvenient for children to understand and use, and requires understanding and memorizing of grammars and complex instructions in a programming language. It is often difficult for them to remember and understand the expertise of program syntax, logical relationships, and program structure.
There are data showing that physical programming has become one of the main forms of programming learning for children. For high-level programming languages, it is necessary to check and compile the syntax of the code language before the code runs. At present, the use of the physical programming lacks the function of syntax check on the physical programming language, so that a user can not know whether the generated effect is correct or not, and the user can not learn correct operation clearly, even with half the effort.
